Letters. Patent No. 70,917, dated .November 12, 1867.

@the Stlgrtule maar tu in tten Enters zttent mit making gaat uf tige time TO ALL PERSONS TO WHOM THESE PRESENTS SHALL COME:

Bc it known that I, ORSON W. STOW, of Plantsville, in the county of Hartford, and State of Connecticut, have made a new and useful invention, having referencev to Machinery for Flanging and Wiring Tinned or Metallic Plate; and I do hereby declare the same to be fully described in the following specification, and represented in the accompanying drawingsn'of which'- I Figure 1 denotes a side elevation,

nFigure 2 a vertical and longitudinal section, and

Figures 3 and 4 transverse and vertical sections of a machine embodying my invention.

The two transverse'secticns are taken through the two sets of boxes of the machine, one section being through the front pair, and the other through the rea-r pair of them.A

The machine exhibited in the drawings is what is termed a tinmahs Hanging machine. My improvement is equally applicable to other machines of like character, viz, such as are'employed for setting down flanges, or for what is termed wiring plate or articles.

On August 30, 1859, a patent was granted to Charles H. Raymond, of Southington, Connecticut, for an improvement in such machines. In the machixne of the said Raymond, the rocker-bearing or shaft is supported by an adjustable stand, separate from, and applied to themain frame by means which admit of such stand being moved, so as to move the shaft of the upper roller in direction of its axis, and for the purpose of adjusting the flanges of the rollers at any desirable distance apart horizontally. The adjustable stand had no screw or equiv alent device for effecting its movement, which had to be accomplished by pressing it in either direction by hand, or by blows given on it by a tool, in consequence of which it becomes a difficult matter to produce a very nice adjustment of the flange of the upper roller, relatively to that of the lower one. Furthermore, owing to wear of the shoulders of the journals of the upper shaft after a while, whereby the shaft is rendered liable to more or less endwise play, a nice adjustment of the two roller-flanges is liable to more or less derangem'ent. All diiiiculties of such a nature are avoided by my invention, or that part of it having reference to the application of the rocker or shaft to the driving or upper rollershaft, and the endwise adjustment of the latter.

In my machine the rocker-Shaft does not move with the driving or roller-shaft while the latter is being adjusted endwise, but remains stationary in its bearings in the frame of themachine, and has screwed into it a tubular adjusting-screw box or bearing, which not only supports the driving-shaft, as a' bearing should, but is applied so as to be capable of being revolved freely on the driving-shaft and against a shoulder thereon, and between the shoulder anda clamp-.nut screwed upon the shaft. The said adjusting-screw bearing has a set-nut, which screws upon it'and against the rocker-shaft, so as to hold the adjusting-screw bearingin its proper place relatively tothe rocker-shaft. By means of the adjusting-screw bearing I am enabled to eifect the endwise movements of the shaft in eitherl direction with great nicety. The clamp-nut prevents endwise pla-y of the shaft, resulting from wear of the shoulders of it and the bearing.

I am aware that, for giving an endwise motion to the shaft'of thc upper roller of a wiring machine, it is not new to employ a movable collar, to turn on the shaft and carry a screw to enter a groove formed obliquely in the shaft, such being as shown in the patent of A. W. Whitney, granted in 1847. My invention, however,

diiers materially from this, as I employ a rotary-screw bearing for the shaft to revolve in, such being screwed directly into theroeker-shaft. And I also employ therewith a set-nut, anda shoulder and screw-clamp, as above mentioned, and hereinafter more particularly explained.

My improvement is productive of new and yuseful effects or advantages. The driving-shaft, during an endwise movement of it, does not move through its front box, as is the case with the machine of Raymond, but it moves with the shaft, it being so applied to the frame as to be capable of endwise motion therein with the driving-shaft; and, furthermore, it can play freely in the'arc of a circle, instead of being moved vertically, or in a straight line on guides. v

By this improved application of the box to its shaft and the frame, such box is not liable top become unevcnly worn, as it is when applied to guides, which cause it, while being -moved upward or downward-,to move in a strictly vertical path. l

In the drawings, A and B are the two anging-ro1lers,'made in the ordinary manner, they being xed' to two shafts C D. A. spur-gear, E, on one shaft, engages with another such gear, G, fixed on `the other shaft. The lower shaft D is supported in boxes H H, each being formed inV two equal parts a a, and placed within one of two recesses b b, made in the main part c of the frame I. This frame is constructed in two portions c d, one of which, viz, the part (Z, answers as a cap to the other, it being fastened thereto by screws c c c e. 1 '.lhe frame completely encases most of the operative mechanism, so as to protect it from dust, as wcll as the dress or parts of an operative from contact with'it.

The rocker-bearing or shaft is shown at K. Its journals ff rest in corresponding bearings g' g, formed in the two parts e (Z of the frame I. It encompasses the shaft C, and has a female screw formed through it, to receive the adjusting bearing L, in which the shaft C rests and revolves. The adjusting bearing L abuts against a shoulder, h, formed on the shaft C, and has a prismatic head, for receiving a wrench, for effecting rotary motion of it.

The clamp-nut M, shown in iig. 2, and also in end and-side views in Figures 5 and 6, screws against the bearing L, and upon a screw, c, cut on the shaft C.

The set-nut of the adjusting-screw bear-ing L is represented at T as screwed upon such bearing 'and against the rocker-.shaft K.

VThe front box of the shaft C is represented at N, its opposite sides being dat and parallel. It embraces the shaft between and against shoulders lm, and rests on a helical spring, n, which serves to raise it while the depression-.screw is in the act of being unscrewed or elevated. The box simply rests against side bearings o o formed in the case, and is free to turn in an are with the shaft.

The guide generally employed with the rollers is shown at S, it being provided with adjusting-screw T.

I make no claim to either of'the machines of the said Raymond and Whitney, no1:` do I claim any parts of either as my invention; but, having described inymachine, what I claim therein as my invention is as follows:

I claim the combination, as well as the arrangement, of the adjusting-screw bearing L with the rocker; shaft K and the roller-shaft C, its shoulder h and clamp-nut M, or their equivalents. i

I also claim the combination vand arrangement of the set-nut T, the rocker-shaft K, and the adjusting bean ing L, applied to the shaftand the case or frame 'of the machine, substantially as specied.

I also claim the application of the front box of the shaft C to such shaft and the case or frame I, so as tol be capable'of being moved ,in one are with the shaft, and endwise withsuch shaft, as described.

I also claim the caso or frame I, as made and applied to the rocker-shaft journals and the bearings of the two shafts, and so as to oncase the gears, substantially as described and represented.
